Addition. I managed to start the GPU S7150 normally at Windows 10, but I can't do it in Windows Server 2019. On the same computer, with exactly the same settings. Maybe it's not about the drive startup modes. Maybe in win Server 2019 turned off support for earlier video cards.]]> Wed, 29 Sep 2021 05:39:08 +0000 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=90449&title=x470d4u-with-pcie-gpu#90449 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=90445&title=x470d4u-with-pcie-gpu#90445 Author: lliax

The BIOS settings from my post above relate primarily to the mxgpu mode setting for the AMD S7150 video card.
I installed Windows today and established the following fact. Integrated graphics work with artifacts when running windows from the legacy disk. Including I was unable to put the drivers for the video card in the pci slot.
In windows startup mode from a UEFI disk, the integrated graphics start and the drivers are installed normally.]]> Wed, 29 Sep 2021 01:29:34 +0000 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=90445&title=x470d4u-with-pcie-gpu#90445 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=89512&title=x470d4u-with-pcie-gpu#89512 Author: NoHTTPS?

Unfortunately, the card s7150x2 doesn't work with virtualization enabled (SR-IOV enabled). BIOS post: dxe pci bus enumeration
I bought a processor 3900X, 128GB RAM for this motherboard. And it turned out that in vain! I will put s7150x2 in the working Intel server based on Supermicro and double Xeon E5-2667v2.

For reference, I confirm that the built-in and external video cards are launched simultaneously when the option is enabled:
BIOS -> Advanced -> Chipset and change the Onboard VGA setting from Auto to Enabled, this way at least the dGPU won't disable the onboard VGA]]> Mon, 18 Jan 2021 23:26:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=83210&title=x470d4u-with-pcie-gpu#83210 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=82006&title=x470d4u-with-pcie-gpu#82006 Author: mrfreitag

I also had the same problem, setting the PCIE to 2x8 instead of 1x16 solved it for me.

I've had the same issue @starkruzr with my smaller gpu (asus b750pi), had to rip out the 980ti from a different build to get it to boot properly.

Has anyone else noticed that regardless of whether the GPU is set as primary it just... doesn't show up in Linux? At all? Like not even in lspci, or in the system inventory in IPMI? I have had this problem both with an AMD GPU with an external power source and an NVidia GPU with just PCIe as the power source. The fans spin, but it's like there's no communication. Both of these cards have been confirmed to work on other machines.]]> Sun, 17 May 2020 12:28:20 +0000 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=75558&title=x470d4u-with-pcie-gpu#75558 https://forum.asrock.com/forum_posts.asp?TID=12812&PID=69653&title=x470d4u-with-pcie-gpu#69653 Author: FLPPasRock

Hope that the options mentioned are going to help you!

But it doesn't solve the issue that the user cannot change the greyed-out setting specifying what GPU should be used as the primary output device :(

Level1Techs is a rather niche tech YouTube channel that recently assisted Gamer's Nexus (another YouTube channel) with the build of a NAS with the ASRock Rack X470D4U2-2T (the same as the X40D4U but with dual 10 GbE onboard):
